!Cards become unresponsive after inactivity | |||
|- | |||
| | |||
'''<u>Symptoms</u>''' | |||
* CCA shows as ''connected''. | |||
* Company cards become unresponsive or show communication errors after a period of inactivity. | |||
* Restarting the '''CCA Windows service''' restores functionality temporarily. | |||
'''<u>Cause</u>''' | |||
* Windows '''USB selective suspend''' may put idle USB ports into a low power state. | |||
* USB smart card readers do not always recover correctly when the port resumes. | |||
* As a result, CCA loses communication with the reader. | |||
'''<u>Workarounds</u>''' <br> | |||
'''<big>Option A</big> — Disable USB selective suspend (recommended)''' | |||
* Control Panel → Hardware and Sound → Power Options | |||
* Change plan settings → Change advanced power settings | |||
* USB settings → USB selective suspend setting → '''Disabled'''. | |||
* Apply for Plugged in (and On battery, if applicable). | |||
'''<big>Option B</big> — Disable USB power management per device''' | |||
* Open '''Device Manager'''. | |||
* Expand '''Universal Serial Bus controllers'''. | |||
* For each '''USB Root Hub''': | |||
** Right click → Properties → Power Management. | |||
** Uncheck '''Allow''' the computer to turn off this device to save power. | |||
'''Notes:'''<br> | |||
* This is a '''Windows power management behavior''', not a CCA defect. | |||
* The issue is more likely to occur on non‑dedicated PCs with active power‑saving settings. | |||
* For dedicated CCA hosts, '''Option A''' is usually the simplest solution. | |||
